IMPROVEMENT IN FENCE.

TO ALL WHOM IT MAY CONGERN:

Be it known that I, JOHN B. JOHNSON, ot' Laurel, in the county et'Franklin, and State of Indiana, have invented a new and usefulImprovement in Fences; and I do hereby declare that the following is afull, clear,

and exact description of the same, referencebeing had to the'annexeddrawings, making part of'this specication, in which- Figure 1 is aperspective view, and Figure 2 is a side elevation. The same letters areemployed in both figures to indicate the same parts. The object ofthisinvention is to provide a cheap mode of constructing portablefences, particularly adapted for lands subject to overflow, by'being soarranged that it may yield to the pressure of a current of waterpand,`

Posts, B, are inserted in the ground to a depth suliieient to give themstability, the upper end projecting,

v D, to which are nailed the boards F. The

panels are made separately, each one being independent ot' the others.These panels are fastened to the'posts B, placed at proper distancesfrom one another,by strong pins, B', passing through the posts B',andtheso through the end posts of the panels D, on one or both sides oflthe posts B. The panels are maintained ins.

vertical position by braces, E, extending from their top to posts A,inserted in the grdund. The braces are fastened to the posts A by pinsA', and to the upper end of the panel-po much weaker than the pins B',which may be also of Wood or of iron.

It will be observed that a fence thus constructed may be very easily setup. Should it be exposed to the remaining in place, may be easilyrestored to position on the subsiding ot' the water.

notion of a current of Water sutlicient to injure it, the pins C, beingthe Weakest part of the fence, will break,

and the panels remain attached to the pests B, and yielding freely tothe action of the water; so also the braces E will be held by the pinsA. As there will be no longer resistance when exposed to the current,the fence will not be carried away, and, on the subsidence of the flood,the fence can be, easily restored to position by putting in new pins C.

I do not cla-im the panels, nor the braces alone nor in combination; but

What I do claim, is'- The mode'of constructing the fence, relation tethe other parts, that they will rst yield to force of currents of water,

and sustaining it by pins C at thc top of the braces, so arranged, inand permit the panels and braces to swing as set forth.
